Li Yan raised her head and looked around the darkness: "what was it that attacked us just now?" Tang Qi pointed to the back wall with a flashlight and said, "it should be these things. This mechanism is really clever." There are four or five extremely sharp blades about one meter above the wall, which have penetrated into the opposite soil wall. If Tang Qi hadn't rescued her just now, her head would have been cut off.

Tang Qi said: "it's better to be careful. This organ should be just the beginning."

Li Yan nervously stood up and looked inside: "how do you know that something is wrong here?"

"Because the sign we saw in the pavilion at the entrance just now is the one with hazy moon. The following sentence should be," the moon comes out in turns, and the mountain weighs ten million. It's the most typical sign. You should be careful in everything. That's right. "

Li Yan smiles: "I didn't expect you to be so superstitious. So how do we go next? Does this door have to be ruled out? "

"Let's observe each other and don't act rashly."

Tang Qi took the stone and threw it into the first hole. Li Yan was so nervous that she could only look at it behind him and wanted to see what the reaction was. The first stone was thrown in and waited for nearly a minute. Then I heard the rumbling sound of water. First I heard the sound that seemed to come from a very distant place, and then there was a bigger rumble, like the tide was coming. Tang Qi quickly pulls Li Yan back a few steps,

there is a whine in the hole, and then a powerful water gun suddenly rushes out. Li Yan watched the wall gush out, splashing out for several meters, then fell directly under their feet, and finally quickly took back. During this period, the water took away a lot of sand and stone bricks on the ground. They were close to the wall and watched the water flow back from their side for a few meters. The whole process was no more than ten seconds, and then the water came back again Flow back, but the ground is quickly restored to dry, there is no trace of water.

If I didn't see it with my own eyes, I would think it was just a dream.

Li Yan nervous said: "this is really too scary! Why is there no trace under your feet? "

Tang Qi said: "it should be that the ground under the feet is not made of ordinary materials. It has a strong penetration ability. Only in this way can the invaders be destroyed directly."

"So it is."

Tang Qi said: "the blade of gold comes out of the water hole in the middle, but the first gold comes out of water. Is it relative? " He picked up another stone and threw it into the hole of the second wood. This reaction happened almost at the same time. At the moment when the stone was thrown in, there was a friction sound inside, and then a thick smoke rushed out quickly, and a group of blue flames flew out, which was very similar to the ghost fire that often appeared in ancient tombs. There was no temperature, and most of them were ignition ratio The lower phosphorus burns up to produce the flame, a group of flames with a diameter of about one foot rushed to Tang Qi and them.

Tang Qi's hands open, and the strong wind blows the fire back. There has been flashing blue flames, Li Yan at this time did not know surprised, frowning at the hole: "wood hole inside is fire. Can the hole in the word "fire" be wood? "

"Let's have a try." Tang Qi said that another stone was thrown in.

But there was no response at all, and there was no sound after waiting for a long time.

Li Yan heart move: "is this the right hole?" Tang Qi shook his head: "since the five elements are relative, I believe that the correct one is the hole of Tu Zi, but the hole doesn't respond. Is it in the air, not on the ground?" After thinking about it, he went to the wall, grabbed the iron piece embedded in it, and then flew out with his transport capacity. Whoosh, whoosh! The sound of piercing the air came from the metal, and then a white light flashed. Tang Qi had been on guard, so he quickly grabbed Li Yan and hid towards the side of the hole. A piece of white wooden arrow flew out quickly and directly into the opposite wall, which could just

reach their height. There are 100. Each bow and arrow is more than one foot long, and its head is very sharp. After starting the mechanism, it flies out automatically. There is a creaking sound in the hole. It seems that more long arrows are not radiated.

Li Yan heart way, today if not and Tang Qi come in together, estimate at this time has died.

Although he had decided to walk through the hole, Tang Qi threw a few things into the cave to test. As expected, everything was normal.

Li Yan Long Tone: "sure enough, there is the right hole, I also worry that my father will have an accident."

"They haven't already been there. What are you worried about?" "But my father told me before that this hole would change the position of the mechanism every once in a while. There was a runner design inside. So last time it was ok, now it's not necessarily OK. He won't let me go, and he won't tell me how to judge. I have to find you. " Li Yan said.

Tang Qi pondered: "this mechanism reminds me of a person. Is this also designed by Xue Yuan? ""As I have heard, is Xue Yuan the famous mechanism master?" Li Yan asked.

Tang Qi nodded: "yes! He is a great scientist. Although he has been dead for a long time, I still admire him very much. If he is a modern man, with the help of current scientific means, I think his mechanism will be even greater. "

But Li Yan laughed: "I think what he represents is the forbidden scientific attitude of old friends, which has nothing to do with dexterity and modern high technology."

Tang Qixin said, if this person lives in modern times, how handsome it is? If only his descendants were here.

Li Yan said, "let's go and hurry to find my father."

Tang Qi nodded and walked into the cave with earth written on it. It's really the name of the place. The land inside is quite difficult to walk. At first, there was a lot of sand and soil, which submerged their vamp. Later, it became deeper and deeper, and the soil became granular gravel. From just to the ankle, it gradually submerged their knees, and then it was beyond their big

legs, and the walking speed became more and more difficult.

Li Yan is out of breath. The inside of her shoes is full of sand. Every step is painful. Tang Qi is also tired of a sweat, reached for a handful of sand, with a flash of light, the flash turned out to be snow-white light, these are white sand, very crystal clear, very beautiful. The quality of the sand is excellent. If I use the sand to do the hourglass business, I will be rich.

Li Yan can no longer walk, she leaned against the wall, constantly panting: "really tired, do not know how long to walk?"

Tang Qi looked back and suddenly said, "something's wrong, Li Yan. Didn't you find anything?"

"What's the matter?" "Look at the road behind us." Tang Qi said to shine a flashlight on the road they must go through. Li Yan was also shocked. It turns out that there are only two very obvious walking routes here. It's her and Tang Qi. Just now, they didn't expect that if their father and Song Jie were walking from here, they should have very obvious footprints. And now with light in front of a careful look at the past, but there is no trace.

Li Yan's brain hummed and said anxiously: "what's the matter? Didn't they go from here? "

Tang Qi said: "just now we have tried the other four roads. Apart from this, there is really no other way. Don't panic. Let me think about what's going on

Li Yan is worried and worried, and her face is constantly sweating. She involuntarily grabs out her mobile phone and wants to call her father, but there is no signal here.

She wiped her face. At this time, she felt that there was something itchy on her right hand, so she grabbed it. There was something cold in her hand. It was not too big. Was it a small stone?

She put this thing in front of her eyes and had a look. She was so scared that she almost fainted. Scream and throw it away.

"What's the matter?" Tang Qi quickly ran to catch her.

At this time, she was shaking like chaff, and her voice was shaking: "mine, that's a spider!"

Tang Qi's flashlight was shining on the sand. In the snow-white sand, a black thing was particularly obvious. It was a fast-moving spider, about the size of longan. He kept moving his body. It was estimated that he was also scared, and then he got into the sand.

Tang Qi said: "it's a spider. Don't be too nervous. It should be nontoxic, or it will bite you just now."

"No! I hate spiders the most. I can't stand it without poison. " She's got goose bumps all over her. It's going to spit out. It seems that even chivalrous women and thieves have their own fears and weaknesses. As soon as Tang Qi's flashlight sweeps the top of the shed, it's also the sound of Nao Weng. It turns out that there are thousands of spiders on the top, all of them are crawling. In the corner, there are all sticky cobwebs, which are piled up in a big group and fluttering in the air.

The distance from them here is no more than one meter. If she knows that her head is full of spiders, Li Yan will be crazy. His flashlight shines in front of her. Fortunately, if there are more than 30 meters, there will be no spiders on it.

Li Yan raised her head and said, "what are you looking at?"

"Nothing. Let's go." Tang Qi covers Li Yan's eyes and pulls her forward quickly. Just now, as soon as they came in, they were accompanied by spiders. It's just what the sand is for. Is it spider dung? Think of here, Tang Qi's whole body is also a shiver, rely on! What's this place, Xue Yuan? Xue Yuan, you praise yourself all the time. How can you use such disgusting

means to deal with us?

Li Yan said, "why don't you go so fast?"

"It's OK. Just walk over."

"But the sand is getting thicker and thicker, and we can't go!" Between speaking, the sand has been submerged to their waist, basically relying on Tang Qi drag Li Yan into the line.And Li Yan's heart is more and more worried for her father, what happened to them in the end! Is there an accident? Why is there no sign of them here?

She was thinking wildly when she suddenly felt that her foot sank, her left foot was empty, and the whole person fell down.

"Tang Qi! I seem to have stepped on something

Tang Qi quickly stretched out his hand to pull her: "what's the matter?" But his feet also followed to step on empty, two people one front and one back, directly fell down from the big pit below, and the white sand beside also followed to fall straight down.
